Comparison of Oral Health-related Quality of Life in Treated and Untreated Class II Adolescent Patients

Aim: This study aimed to investigate the effect of growth modification treatments on oral health-related quality of life in adolescents aged 11 to 14 years with Class II malocclusion. Methods: Eighty people participated in this case-control study. The case group (n=43) included adolescents with a history of Class II malocclusion treated with growth modification. The control group consisted of 37 adolescents with Class II malocclusion who were not treated. Both groups were given a translation of the Child Perception Questionnaire (CPQ), measuring the quality of life in four domains: oral symptoms, functional limitations, psychological health, and social well-being. Data were statistically analyzed by SPSS software and a significance level of 0.05 was considered. Results: The oral health-related quality of life of the case group was better than the control group in all areas although this difference was not statistically significant (P=0.204). Conclusion: The oral health-related quality of life between two groups was not different; however, the difference in mental health components between the two groups was clinically negligible.
